# This way of fetching the tar-file separate from the docker commands makes
# http-proxy handling way easier. The wget command handles the $https_proxy
# variable while the docker command must have /etc/docker/something changed
# and the docker server restarted. That is not possible without root access.

# Make a Dockerfile. This method simplifies env variable handling considerably:
